Every change Wellknown observed on this MCP server, newest first, with what it was before and what it became. Tool-surface changes carry the definition diff. Nothing here is edited after the fact.
Added "get_base_pack" (10 tools before, 11 now)
What do I need to know to move USDC on Base: chain facts, USDC token facts and which providers on-ramp or off-ramp there? Paid ($0.01 USDC): One call, three cited datasets for Base: the /v1/chain record, the /v1/token record for USDC on Base, and every dataset provider that lists Base and on-ramp and/or off-ramp (id, name, onramp/offramp flags, source_url, retrieved_at, quote, confidence). Includes as_of and a sources list. No parameters. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-pro…

Added "check_rail_calendar" and "check_regulator" (8 tools before, 10 now)
Is this payment rail closed on this date, or on which days is it closed this year? Free: rule-based closing days for TARGET (ECB T2), Ireland and UK bank holiday calendars (England and Wales, Scotland, Northern Ireland). Give date=YYYY-MM-DD for closed true/false with reason, or year=YYYY for the list of closures. TARGET also closes on weekends; IE and UK calendars list holidays only. IE weekend substitution days are not modelled. 60 calls/min per client.
Is this firm on the ESMA MiCA register (CASP, e-money token issuer, white paper, or non-compliant warning list)? Free: look up a firm in the ESMA interim MiCA register by name (exact or fuzzy) or LEI, optionally narrowed by country. Returns match_quality, an ambiguous flag, candidate records with status, competent authority and source URL, plus ESMA attribution and register links. Absence from the register is not clearance. 60 calls/min per client.
Added "get_token" (7 tools before, 8 now)
What are the symbol, name, decimals, contract address and issuer of this stablecoin on this chain? Paid ($0.001 USDC): Cited stablecoin token facts from a prepared dataset (USDC, EURC, USDT, PYUSD, DAI on the chains /v1/chain covers, where a permissively licensed source lists them): symbol, name, decimals, contract address, chain, issuer, each with a source citation and license. Fields not established from a source are the string "unknown". Malformed input and tokens not in the dataset return 400/404 and are never charged. This server holds no wallet and never pays: it returns the HTTP 402 pa…
Added "check_address_format" and "get_chain" (5 tools before, 7 now)
Is this address well formed for this chain, and what is its EIP-55 checksummed form? Free: deterministic address format check for EVM chains (EIP-55 checksum: valid, checksummed form, whether the input checksum was correct, all lowercase or all uppercase) and Solana (base58, 32 bytes). No external calls. 60 calls/min per client. Format only; says nothing about who controls an address.
What are the basic facts of this chain (CAIP-2 id, gas token, explorer, x402/MPP settlement, stablecoins)? Paid ($0.001 USDC): Cited chain facts from a prepared dataset: CAIP-2 chain id, gas token, finality class, block explorer, whether x402 and MPP settle there, and stablecoins. Fields not established from a source are the string "unknown". Unknown chains and malformed input return 404/400 and are never charged. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1…
Added "get_examples" (4 tools before, 5 now)
What do the paid endpoints return, and what do they cost? Free: prices and paths of every paid endpoint, plus a full example response for GET /v1/provider taken verbatim from a real record, labelled as an example with its last-verified date. Use it to see the shape and depth of paid data before paying.
